Pulverized Coal Explosions in the U.S. Utility Industry

Ignition events remaining within the coal pipe created only weak pressure rise, while ignition events within a simulated pulverizer volume created explosions exceeding 70 bar gage (1015 psig). These experiments showed that explosion characteristics depend on dust concentration, ratio of pulverizer volume to coal pipe area, as well as coal type.

Dynamic steam inerting system for a ball tube mill

Aug 01, 1980 Coal pulverizing system explosions during the last few years have pointed to the need of developing inerting systems for preventing such incidents. The greater use of western subbituminous coals (with their higher tendency for spontaneous ignition) is a contributing factor to the increased frequency of coal pulverizer explosions.

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners.
